toning down the ps audio perfect wave dac

i own an original ps audio perfect wave dac. i called ps audio about sending it back for an upgrade. a technician i spoke to said the upgrade would increase the resolution of the dac.

i would like to tone down the treble a bit, as i find it a bit treble heavy.

i thought the least expensive way of doing this is substituting caps in the signal path and or replacing the metal film resistors with reiken carbon fibers.

i am not familiar with the "sound" of caps, but would like to soften the treble.

the only caps i am aware that might do that are audio note, mundorf or duland. am i on the right track ?

if not, what other caps could i consider ?

I will answer your question directly rather then taking you different placeS already done. You will wan't PIO - paper in oil caps. Ampohm will do what you want. They have several still available and tend to focus more on the mids. I think The Tube Store still has some available. The tin foil, aluminum or copper ones are fine. I would try to get the tin foil or copper ones.

Based on seeing your posts over the years and your dislike of any tipped or bright highs, these are for you. Give them 50 hours before reaching any conclusion.

They are large however and may or may not fit.

Another choice if PIO will not fit are AudioCap Theta's. They are film caps and much smaller. Very warm and non-fatiguing.

Two great, lower cost options. This step will in fact give you what you are looking for based on my experience rolling caps in gear.
